6SixTy··on Ask HN: Linux on Snapdragon X Laptops?
Don't see why it wouldn't work, as UEFI is basically a hard requirement for running Windows. With UEFI support, there's a lot of functionality that's assumed to be there (e.g. basic graphics) that the question becomes "is this actually good?" rather than "can this work?".
6SixTy··on Qualcomm wins licensing fight with Arm over chip designs
Doesn't mean that it is compiled with Vector support or optimizations, which is going to artificially make the results worse.
6SixTy··on Qualcomm wins licensing fight with Arm over chip designs
How is Geekbench any good at comparing RISC-V to ARM? Geekbench isn't a native RISC-V application, let alone has the wherewithal to correctly report any basic information like frequency or core count. You haven't even prefaced these either, and drew conclusions from them.

Also, actually searching the chip in question is impossible.

6SixTy··on How the White House Functioned with a Diminished Biden in Charge
Given the age range of candidates from Clinton/Bush Jr. to now, and how neither side is worried that their candidates will end eventually up like Reagan, there's a good chance that something behind the scenes is happening.
6SixTy··on Top Marine says combat experience gives US the edge over China's military
Perhaps, but the Sino-Vietnamese War is nearing 40 years old by now. A lot of combat experience and grand strategy from then is completely irrelevant by now. Arguing over how much the basic infantry experience has changed from then to now is one thing, but gaining a significant naval and air power when your last major conflict had zero such thing is another.

That's primarily the reason why the PLA shouldn't be taken seriously. They are mechanizing their military with zero real idea what makes them any good.

6SixTy··on China kicks off homegrown Bluetooth alternative – Star Flash
Doing some dead reckoning translation work from the Chinese news source, this seems more like reheating Huawei's Nearlink for the broader Chinese market than making a new technology.

Also good chance Star Flash's actual name in English is SparkLink.

6SixTy··on Apple Reportedly Redesigning Magic Mouse
Apple hasn't really been known for good mice especially since they switched to usb. Their best mouse was the Mighty Mouse and not by much.

The entire magic mouse concept is half baked since it relies too much on invisible touch areas for much of it's functionality. It's also way too thin for most people to use comfortably for extended periods of time. It's a really bad design overall but the bottom mounted charging port was the straw that broke the camels back.

Apple could release a "pro" mouse that mostly copies the functionality and form of the MX Master 3s, and it would likely be a home run.

6SixTy··on AT&T won't upgrade millions of DSL users to fiber despite billions in subsidies
Problem is that we live in an environment where a company like AT&T can lobby for basically anything they want, and have basically no accountability when they don't meet their obligations.

You even have people telling stories where they could get fiber service, but the provider just doesn't want to.

6SixTy··on RISC-V HiFive Premier P550 Development Boards with Ubuntu Now Available
Honestly, this type of board is something that you aren't really going to just install in a case and forget about it. You are most likely going to have this on a test bench so you can swap out all kinds of different hardware for validation.

Buttons on the bottom for power/reset, 2 different JTAG ports, DIP switches for settings, and remote board management aren't things that are normally found on consumer boards. Mini DTX probably allows them to have a marginally smaller width compared to Micro-ATX while still allowing space for all of that debug functionality with a 2 slot graphics card installed. eMMC is also kind of important for a SOM as well.

6SixTy··on RISC-V HiFive Premier P550 Development Boards with Ubuntu Now Available
it takes time (~2 years) for silicon designers to go from idea to taping out silicon. The P550's cores are advertised as having good area efficiency, so it could be both getting rid of the vector extensions to optimize area and they just couldn't incorporate them into the design.

I is the base integer instructions

M is integer multiplication

A is atomic

F is single precision float

D is double precision

G is shorthand for all of the above + 2 others that I honestly have no idea what they do

6SixTy··on Raspberry Pi 500 Review: The keyboard is the computer, again
Those things are cool in their own right, but most of those belong within the context of someone looking to make something or learn electronics. Not necessarily something that someone looking to use one as a fully fledged computer is going to appreciate. And the Pi 500 definitely swings in the direction of computer.
6SixTy··on Why are cassette and CD players so bulky now? [video]
Cost. These "new" products are doing the bare minimum needed turning extant mechanisms into a product, than make bespoke tooling for a specific performance envelope.

Cassettes are definitely a hipster kind of thing, CDs aren't as they are pretty much the only way you can have music digitally without having it taken from you. Pretty much nobody that buys CDs actually plays them regularly, they just rip it at home and use that instead.

6SixTy··on Mend it Mark gets suspect copyright strike for £25k audio amp repair
Even leads for monitoring brain activity don't do that stuff. And they are monitoring literally mV. Leads and contact patches are often made of silver to capture that stuff too, and they have actual reasons to use silver.
6SixTy··on Windows on ARM Gets Major Gaming Boost with Prism Update
Those are way better links. Just knowing that the wallpaper on my 2nd screen is going to be fixed solves a pretty big bugbear for me.
6SixTy··on Payments Are Going Digital, but Many Seniors Still Rely on Cash
Google Pay still exists. It hasn't died per se, just bounced around a bunch of Google apps before the core functionality got subsumed into what is now Google Wallet. There's an entire flowchart on Wikipedia it's that bad.
6SixTy··on Researchers get 'compact' hard X-ray machine to work
Far as I know, X-Ray lithography is even harder than EUV. Mostly because optical manipulation of X Rays barely exist, and X Rays only interact with heavier elements.
6SixTy··on Humane wants to put the AI Pin's software inside your phone, car, and speaker
What are the chances that the software is just a version of Android, maybe Linux? Google could barely put out a few devices using Fuschia doing the same thing basically.
6SixTy··on Intel announces Arc B-series "Battlemage" discrete graphics with Linux support
On paper any PCIe 2.0 motherboard can receive a BIOS update adding ReBAR support with 2.1, but reality is that you pretty much have to get a PCIe 3.0 motherboard to have any chance of having it or modding it in yourself.

Another issue is that not every GPU actually supports ReBAR, I'm reasonably certain the Nvidia drivers turn it off for some titles, and pretty much the only vendor that reliably wants ReBAR on at all times is Intel Arc.

I also personally wouldn't say that Sandy Bridge is very usable with a modern GPU without also specifying what kind of CPU or GPU. Or context in how it's being used.

6SixTy··on Intel announces Arc B-series "Battlemage" discrete graphics with Linux support
A not inconsequential possibility is that both the iGPU and dGPU are sharing the transcoding workload, rather than the dGPU replacing the iGPU. It's a fairly forgotten feature of Intel Arc, but I don't blame anyone because the help articles are dusty to say the least.
6SixTy··on Vulkan Video Now Enabled by Default for Radeon VCN2/VCN3 Hardware on Linux
Apparently Android's multimedia security system and driver model are incompatible with Vulkan Video. https://issuetracker.google.com/issues/293419320?pli=1
6SixTy··on Vulkan Video Now Enabled by Default for Radeon VCN2/VCN3 Hardware on Linux
Seems like an effort to stick video en/decoding behind graphics drivers as a vendor neutral approach instead of relying on VDPAU or VA-API. These efforts should equally apply to Windows and Android as well as Linux.

Kill switches across the battery aren't terribly uncommon
6SixTy··on What does this button do? – My new car has a mysterious and undocumented switch
Problem with gathering data off cars is that it's really not that effective vs your phone. A car realistically just sits around doing nothing 80% of the time, while a phone is with you 24/7, likely powered 24/7, and already has telemetry mechanisms built in. An old car with someone using a phone probably still collects the same data as you assert.

And an EV without smarts is legitimately just a golf cart.

6SixTy··on M4 Mac Mini Cluster [video]
It's genuinely terrifying how narrow the use cases are for a Mac, and how much power Apple is shamelessly stuffing into them.
6SixTy··on Ubitium is developing 'universal' processor combining CPU, GPU, DSP, and FPGA
Transmeta's whole elevator pitch was a power efficient CPU that through translation software, happened to run x86 instructions so there's no porting nonsense necessary. Only issue was that they made it 1/x efficient, at 1/x the speed.

Interesting fact is that the guy who architected Transmeta's CPUs also worked on Itanium and Russia's Elbrus CPUs. The Elbrus is sort of a spiritual successor to Transmeta's efforts at this translation thing, but it is very much aimed as a hardware root of trust solution to sandboxing software rather than a genuine effort at competing in foreign markets.

6SixTy··on Half of young Norwegians say online piracy is an acceptable way to save money
For creative works, there's always a license behind it post the invention of copyright. It wasn't as obvious in the past now that DRM and digital/streaming only has given studios/publishers/etc the ability to cancel your access at their discretion. Though complicating matters is that there's increasingly nothing worth spending money on in the first place anymore.
6SixTy··on Mercedes spends $8bn/year on R&D
Thing about flying cars is that you can either have a good car or a good aircraft. Having both combined is worse at both and more expensive at both. Not to mention the headache of dealing with the FAA and whoever does vehicles to get it air and road worthy.

In any case, we have helicopters which embodies the spirit of a flying car

6SixTy··on The meme-ification of the “Demon Core”
OSHA 30 hour here: no the f** it isn't. You only lose an eye once before it's just gone. Hearing can only get worse. Some stuff will just kill you, some more slowly than others. Only literal children can bounce back from a what would otherwise be a fatal injury, but that's a very narrow slice of how you can get hurt.
6SixTy··on Bpftune uses BPF to auto-tune Linux systems
I second the different profiles for server, laptop, and so on. Though I know the kernel already comes with default configs, so I think there could be room for specialized kernel config options in addition to what's already there.

Though in my opinion, there's already kind of too much segmentation between the different use cases. A server is just a role for a computer, and embedded could literally mean anything. Quite a few WiFi access points come with a USB port on them so you can plug in a USB drive and start a SMB server.
